simple question programming arduino

hi, i have arduinos connected: pin1 (of arduino1) connected pin3 (of arduino2). pin1 (of arduino 1) output. pin3 (of arduino 2) input. i want set pin4 of arduino_2 high, when receives signal arduino_1 @ pin3. what instructions code write arduino_2? (just instructions) when send signal arduino_1,  pin_3 of arduino_2 set high? i think 2 arduinos need common ground. kind of topic has been covered many times on forum. do quick search , see pops up.. lots of different ways of connecting them too, not digital pins.

bonjour, en démontent un thermomètre j'ai trouver l'intérieur une puce nommée "mc14051bcp", j'ai trouver son datasheet http://www.onsemi.com/pub_link/collateral/mc14051b-d.pdf , d'après se que j'ai pu comprendre ses un multiplexeur analogique qui pourrais servir pour les switches, par contre je ne comprend pas le chéma d'utilisation, sinon ma question est de savoir si cette puce est exploitable avec l'arduino, et si oui comment l'utiliser ou m'aider comprendre son shémat, merci d'avances. bonjour un multiplexeur analogique, c'est un peu comme un gros interrupteur commandé électriquement. en fonction du nombre écrit en binaire sur les entrées a, b et c (3 bits donc 8 possibilités 0.. le composant effectue un lien entre la borche xn correspondante et la broche x (le commun). c'est une liaison analogique, c'est à dire que la tension est transmise intégralement. tu peux par exemple t'e...

Low Battery Monitoring for LiPo

i want connect lipo battery analog input on arduino, i'm not sure if should connect through resistor or not? lipo --> analog input or lipo --> resistor --> analog input what guys recommend? what pros , cons? if talking less 5v can connect directly, recommend using series resistor , it's not bad idea add capacitor filtering. resistor few k ohms 100k should good.

SPI,I2C interfaces in Pi - Raspberry Pi Forums

hi, going through article : http://www.airspayce.com/mikem/bcm2835/ under heading "real time performance constraints" talks constraints , says "this means should not expect real-time performance or real-time timing constraints such programs." questions are 1. what's solution of problem in pi's context. how can make part of kernel ? 2.how in other devices, mobile phones, such interfaces work in real-time.say applications , games designed using accelerometer on mobile phone reacts in real-time . regards, tk a short answer pi wasn't designed real time. rather multi purpose teaching tool. there many things going on in background interrupt such applications , can cause small delays. in applications isn't issue true real time tiny delay can cause issues. question 2 don't believe many examples category considered real time rather data doesn't change fast enough real time application. 1 reason arduino products suit these situations ...

l298n motor control board

i'm embarrassed have ask this, can't figure out how use l298n motor controller board found on ebay.  thought easy use, can't figure out.  right trying out different things multimeter.  output voltage seems keep fluctuating between -0.2v , +0.2v.  pins have are: motor 1(positive , negative), motor 2(positive , negative), vcc (motor voltage),gnd,5v (logic stuff).  have 8 pinheads sticking out ("in1"-4,"ena","enb" , 2x "5v").  2 jumpers came it. right connected vcc +5 on arduino (remember testing, once use motor change that), gnd gnd , +5v pin 11.  tried few different things, 1 expected work pwm.  didn't.  confirmed (using multimeter) giving 3.5pwmvolts logic input. what forgetting?  know it's pretty obvious. i've bought l298n board on ebay. got mine work -> http://www.bajdi.com/arduino-rc-car-part-1-motor-control/ ...
